Creative Sound Blaster X-Fi Xtrememusic SB0460 Problem

I installed Windows 7 professional 64 bit on a clean partition of my Win XP computer, as a dual boot configuration. Everything installed fine with the exception of the sound card. It is a Creative Soundblaster X-Fi xtrememusic, model SB0460.

In device manager it is listed as "Other Devices > Multimedia audio controller" instead of a sound card.

I downloaded and tried to install the latest 64 bit drivers from Creative, but it failed because it could not "find" the card.

Attempting to manually install a generic driver from device manager fails because Creative is not even on the list

of manufacturers.

When I ran Windows 7 upgrade advisor, it found no problems and indicated that the sound card was compatible.

It runs flawlessly in XP, so I am stumped as to a solution.

The initial response was this:

Shut down the PC, open the case the physically remove the card from its slot. Restart the PC. Leave it running a few minutes then shut it down again and replace the card. Restart the PC. Does Windows 7 now 'see' it?

I tried the suggested solution, but the result was the same. I even moved the card to another PCI slot, without success. Apparently, if the sound card does not show up under "Sound, Video and game controllers" in Device Manager, the Creative driver installer cannot "find" the device.

Any ideas?
